I agree that some things cannot be produced well cheaply, so if you buy cheap you will by twice. But torches do not have moving parts that wear out easily, even if they're made from cheap materials. But aircraft grade aluminium, 7075, is cheap, as is brass, no matter who the manufacturer is, but more importantly who the trademark owner is, because they're all made on Chinese production lines no matter what badge they end up with. Maybe the paint will wear off an UltraFire faster than it will off a SureFire, but they'll both either fail quickly due to some manufacturing fault, or go on for donkey's years.
